![]() ![]() After charging for 90 minutes for the third time, the battery should be used for 30 minutes to measure its internal resistance with the battery internal resistance tester.ī. ![]() 5.Detection of battery internal resistance:Ī. Cycle three times to calculate the last discharge capacity. Charge the battery for 90 minutes and record the highest voltage when charging, set aside for 30 minutes and then discharge to 1.0V/ CELL. Before the first charge, the battery should be discharged to a single 1.0V, and then the battery should be charged for testing 0.2C.ī. redness around the positive electrode cap) and record the open circuit voltage. Before the test, the battery should be numbered on the battery first, and phenolphthalein should be used to test whether the battery has alkali crawling, liquid leakage (i.e. The open-circuit voltage of ni-MH batteries must be greater than 1.25V when all batteries in stock are shelved for more than 15 days.1.0-1.24V is grade TWO, and below 1.0V is waste.Ī. Battery voltage greater than 1.15V/ CELL is qualified, 0.8V-1.14V/ CELL is second grade, 0.8V-0.5V is defective, and 0.5V is waste (applicable to Ni-CD battery).Ĭ. All incoming battery open circuit voltage must be greater than 1.2V/ CELL (not charged) or greater than 1.25V CELL (charged) (for NI-CD batteries).ī. "Great experience buying from this retailer, item was shipped in a timely manner and was exactly as described.Batteries placed in the inspection area are sampled at the AQL-J1 level specified in the sampling standard.The minimum sample quantity of each lot shall not be less than 30 PCS.Ī.
